The Checklist of North American Mammals North of Mexico, 2003 has been revised to include recent taxonomic changes and additions, as well as to include new distribution records and introductions for this region. In this revision, 495 species, 180 genera, 48 families, and 12 orders are recognized, resulting in a net gain of 21 species, 14 genera, and 2 families since 2003. Relative to the 1973 version, the change in number of species resulted from 54 taxonomic changes, 12 distribution changes, addition of 27 introduced species, and one extinction. The greatest change since the initial checklist in 1973 has been in the number of genera (+28.4%), followed by species (+22.8%)
